| 摘 要： | 采用室内试验方法,对广东省云浮地区块状煤系土的物理力学性质进行研究,重点论述了块状煤系土抗剪强度的变化规律,建立了具有实用价值的经验性公式.研究结果表明含水率与强度关系密切,粘聚力受含水率影响较大,内摩擦角受含水率影响较小.通过室内试验和理论分析,为工程中合理利用煤系土提供借鉴依据.

| Abstract: | According to the results of tests in laboratory,the geotechnical properties and some laws of shear strengthproperties of the giant soil of coal measure strata are discussed empheatically. And the paper gives the empiricalformulas with practical value. The research would indicate that its water content is closely related to shear strength,and cohesive strength is affected greatly by water content while friction angle is small. It will be helpful in the actualprojects through the tests and theoretical research. |
